Application filed August 30, 1911. Serial No. 646,907.

To all whom it may concern: y

Be it known that I, HARVEY It HIPPLE,

.a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Nut and 'Bolt Locks, of which the following is a specification, reference being had therein to the accompanying drawing. w

This invention relates to a bolt and nut lockof that class where it is'intended to secure the nut upon the boltin such a way as to prevent its becoming loosened, and it relates more particularly to that class of bolts used on railroad rails, where it is important to have 'a device of vthis class that shall not only be 'efective but capable of repeated use.

The object of the invention is to provide a lock boltY and nut of this class that shall be cheap, durablevand efficient and capable of repeated use.

Another object of the invent-ion being to provide a novel locking means whichv shall not reduce the strength of the bolt.

Still another object being to provide an article of this kind that is not only capable of preventing the loosening of the nut, .but which may be used as a stop and set at a predetermined place upon the bolt to preventpthe nut. from being set up and tight# cned.

With these and other objects in view, my'

invention consists in certain. construction and combination of parts as will hereinafter be -fully described and claimed in the annexed specication and illustrated-'in the accompanying drawings which4 form a part of this application and in which like ligures of reference refer to corresponding parts in all of the views; but it is fully understood that while I have here described my invention as shown, that I do not confine myself to the exact design, as slight changes may be made in the construction and arrangement of the several parts without departing from the spirit of the invention.

In the drawings Figure 1, is a side elevation of a bolt and'nut partly in section embodying my invention. Fig. 2, is'a plan view of the lock washer.A Fig. 3, is a side elevation of the same.

I claim as new and desire to Referring to the drawings, the invention comprises the usual bolt- 1, provided with the threads 2, and having'a v longitudinal key-way 3, and the usual nut 4.

The locking device consists ofl a washer 5, of semi-flexible materialv such as.. soft steel and is formed withut-he ears 6, and the key 8, which allows the washerl 5, to be placed upon the boltwl, and prevented .from turning thereon by the keyA7, engaging the key-way 8. a

When thenut Ltis drawnrup'to the required place, the-ears 6, va-rebent over u pon t-he sides of the nut' 4 andwill thus prevent the nut 4, .from turning upon the bolt, as shown in Fig. 1, and yet 'the ears 6, may be straightened out and the nut -removed; `andthis operation may be repeated a great many times before the ears will become weakened.

As shown in Figs. 1, 2, and 3, the key- 8 is bent at right angles to the washer 5, and provided with the screw-threads 9, in -such 'a way that when the same is placed upon the bolt, the threads 9, will register with the.

threads' of the bolt, and in this manner the washer may be setat any desired place upon the bolt and-when the nut drawn up and engages the threads 9, on the key 8,'

the washer will serve as a stop and `prevent the nut from going farther on the bolt.

Having thus described my invention what secure byLetters Patent is y .f yIn a nut lock o'fthe class described, the combination with" a bolt and a nut, said bolt being provided with a. longitudinal key-way, of a washer adaptedyto iit overi said bolt, a key formed fon said washer and adapted 'to engagesaid key-way, threads formed on said key,the threads of said key adapted to be engaged by the nut to prevent said washer fromv sliding on said bolt, of ears formed onfsaid washer and adapted to be bent to engagethe surface of said nut to `preventthe same fro'mturning on said bolt.

In testimony whereof Ialiix my signature in presence of two witnesses.'
